  1 Cycle = 4 weeks: Day 1,8,15 in a 28 day cycle; 3 consecutive weeks (weeks 1, 2, and 3) of chemotherapy with 1 week off, OR

  1 Cycle = 4 weeks: Day 1, 15 in a 28 day cycle; Every other week (weeks 1 and 3) of chemotherapy with 2nd and 4th week off
* mFOLFIRINOX: Oxaliplatin, 85 mg/m² IV once every two weeks over 2 hours on Day 1 Irinotecan, 150 mg/m² IV once every two weeks over 90 minutes on Day 1 5-FU, 2,400 mg/m² IV once every two weeks over 46-48 hours administered via infusion Leucovorin, 400 mg/m2 IV every two weeks over 90 minutes on Day 1

  1. Cycle = 4 weeks, administration on Day 1 and Day 15 of each mFOLIRINOX cycle

The intervention will be administered on an outpatient basis. The patients on this study will begin treatment with GA for one month and then transition to mFFX for one month.

The patient will come off of the sequence study intervention if the imaging after the 2nd month shows unequivocal progression. After four months of sequential neoadjuvant therapy the patient will come off study and can proceed to surgery, radiation, or extended course of chemotherapy as determined by the multidisciplinary tumor board consensus or the treating physician.

CT imaging of chest abdomen and pelvis will be performed every 8 weeks. MRI may be used.

Study Coordinator

Ravi K Paluri, MD, MPH

The objective of this research is to find out what effects (good and bad), the sequence of Gemcitabine - Abraxane (nab-Paclitaxel) followed by mFOLFIRINOX, the standard chemotherapy for pancreatic cancer, has on participants and their condition. Gemcitabine - Abraxane (nab-Paclitaxel) and mFOLFIRINOX has been approved by the US Food and Drug Administration (FDA) as first line treatment for advanced pancreatic cancer. The sequence of Gemcitabine - Abraxane (nab-Paclitaxel) followed by mFOLFIRINOX has not been approved by the FDA for treatment of pancreatic cancer.

Primary Objective:

- The primary objective of this study is to evaluate the efficacy of sequential Gemcitabine - Abraxane (nab-Paclitaxel) followed by mFOLFIRINOX in improving R0 resection rate in patients with borderline resectable pancreatic cancer and locally advanced unresectable pancreatic cancer.

Secondary Objectives:

* Evaluate the safety and tolerability of sequential Gemcitabine - Abraxane (nab-Paclitaxel) followed by mFOLFIRINOX in patients with borderline resectable pancreatic cancer and locally advanced unresectable pancreatic cancer
* Evaluate progression-free survival (PFS) in patients treated with sequential Gemcitabine - Abraxane (nab-Paclitaxel) followed by mFOLFIRINOX in patients with borderline resectable pancreatic cancer and locally advanced unresectable pancreatic cancer according to Response Evaluation Criteria in Solid Tumors (RECIST 1.1) guidelines
* Evaluate overall survival (OS) in patients treated with sequential Gemcitabine - Abraxane (nab-Paclitaxel) followed by mFOLFIRINOX in patients with borderline resectable pancreatic cancer and locally advanced unresectable pancreatic cancer
* Evaluate the objective response rate (ORR) in patients treated with sequential Gemcitabine - Abraxane (nab-Paclitaxel) followed by mFOLFIRINOX in patients with borderline resectable pancreatic cancer and locally advanced unresectable pancreatic cancer.
* Evaluate the disease control rate (DCR) in patients treated with Gemcitabine - Abraxane (nab-Paclitaxel) followed by mFOLFIRINOX in patients with borderline resectable pancreatic cancer and locally advanced unresectable pancreatic cancer.

Neoadjuvant Chemotherapy for Borderline Resectable and Locally Advanced Pancreatic Adenocarcinoma

Sequential Neoadjuvant Chemotherapy for Borderline Resectable and Locally Advanced Pancreatic Adenocarcinoma

The R0 resection is assessed only in patients who undergo surgery. R0 resection is a microscopically margin-negative resection, in which no gross or microscopic tumor remains in the primary tumor bed. Participants are considered to be evaluable if they receive at least one sequence of treatments with GA and mFFX (1 cycle GA followed by 1 cycle of m FFX). Primary analysis for each cohort will calculate the R0 resection rate with one-sided 95% confidence interval.

The incidence of treatment-emergent toxicities/adverse events (AEs) and Serious Adverse Events (SAEs) in terms categorized and graded according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE version 5). Incidence tables will be generated to summarize incidence of patients reporting at least one episode of each specific adverse event, incidence of adverse events causing withdrawals and incidence of serious adverse events, separated by cohort.

The number of participants to complete 4 cycles of sequential chemotherapy.

Progression free survival (PFS) is defined from the day of study treatment initiation until progression according to RECIST v 1.1 guidelines (d. Progression: One or more of the following must occur: 20% increase in the sum of appropriate diameters of target measurable lesions over smallest sum observed (over baseline if no decrease during therapy) using the same techniques as baseline, as well as an absolute increase of at least 0.5 cm. Unequivocal progression of non-measurable disease in the opinion of the treating physician) or death of any cause, whichever occurs first, as measured throughout the study. Stratified Kaplan-Meier curves will be constructed to assess PFS with estimated 6-month and median times with 95% confidence intervals

Overall survival (OS) is defined from the time of study treatment initiation until death of any cause. Stratified Kaplan-Meier curves will be constructed to assess OS with estimated 6-month and median times with 95% confidence intervals

Tumor response based on computed tomography (CT) scans or magnetic resonance imaging (MRI) scans. These will be evaluated according to the RECISTv1.1 criteria using a summarized count/percent with one-sided 95% confidence interval for each cohort:

Measurable disease: Lesions that can be accurately measured in at least one dimension (longest diameter to be recorded) as ≥ 2.0 cm by chest x-ray, by ≥ 1.0 cm with CT or MRI scans, or ≥ 1.0 cm with calipers by clinical exam.

- Malignant lymph nodes are to be considered pathologically enlarged and measurable if it measures ≥ 1.5 cm in short axis (greatest diameter perpendicular to the long axis of the lymph node) when assessed by scan (CT scan slice recommended being no greater than 0.5 cm).

Non-measurable disease: All other lesions (or sites of disease), including small lesions (longest diameter \< 1.0 cm or pathologic lymph nodes with ≥ 1.0 cm to \< 1.5 cm short axis).

Treatment response is defined as the proportion of patients with a disease control rate (complete + partial response + stable disease) based on RECISTv1.1 criteria using a summarized count/percent with one-sided 95% confidence interval for each cohort.

Complete Response (CR): Complete disappearance of all target and non-target lesions (with the exception of lymph nodes mentioned below). No new lesions. No disease related symptoms.

Partial Response (PR): Applies only to patients with at least one measurable lesion. Greater than or equal to 30% decrease under baseline of the sum of appropriate diameters of all target measurable lesions.

Stable: Does not qualify for CR, PR, Progression or Symptomatic Deterioration. All target measurable lesions must be assessed using the same techniques as baseline.
